Product information
Our round tank sight glasses type 390V are designed for vacuum applications from -0.9 barg to 16 barg. They are welded onto a pipe socket or into a container wall to allow observation or illumination of the interior of the container. In doing so, a sight glass made of chemically highly resistant borosilicate glass DIN7080 is clamped between two high-quality stainless steel flanges and proven quality seals.
Our round tank sight glasses type 390V are made from high-quality stainless steel 1.4571 (316Ti), which our customers have appreciated for years. As glass material, the industry-proven borosilicate glass according to DIN 7080 (or according to customer specifications) is used.
The sealing of the fitting is done with D- or O-ring gaskets adapted to your needs from a wide range of materials such as PTFE (Teflon®), NBR, silicone, EPDM, FKM.
FEP- or Halar® coatings additionally protect the borosilicate glass from aggressive chemicals or alkalis.
Like other sight glass fittings from our range, the type 390V can be equipped with LED lights upon request.
